我有一个使用Doctrine MongoDB ODM的Symfony 2应用程序,我正在尝试使用PHP 7运行它.

我已经成功安装了PHP 7,但是通过Composer安装依赖项让我感到悲伤,出现以下错误:

doctrine/mongodb 1.0.x-dev requires ext-mongo >=1.2.12,<1.7-dev -> the requested PHP extension mongo is missing from your system.

我设法通过apt安装PHP 7 mongo扩展:

apt-get install php7.0-mongo

为了确定,我还mongodb通过PECL 安装了扩展:

sudo apt-get install -y php-pear php7.0-dev libcurl3-openssl-dev
sudo pecl install mongodb

但是,我仍然得到无法找到mongo扩展名的错误.似乎存在版本差异,ext-mongo >=1.2.12但只是1.1.6安装了::

$ php -i | grep mongo
/etc/php/7.0/cli/conf.d/20-mongodb.ini,
mongodb
mongodb support => enabled
mongodb version => 1.1.6
mongodb stability => stable
libmongoc version => 1.3.5
mongodb.debug => no value => no …

即使我阅读了手册,我也很难理解FILES _ $ {PN}.例如,我正在研究制作启动脚本的这个例子.在我写了类似的东西之后,我收到了这些错误消息.

就上下文而言，对驱动程序进行编程以与Xilinx板上的嵌入式Linux（Yocto：krogoth）上的FPGA IP内核进行交互。

为了调试，我想从物理内存中读取特定的内存地址。/ dev / mem看起来很有希望。我想问一下如何从命令行中读取特定物理内存地址的值。我希望可以cat /dev/mem 0x2000000通过读取0x2000000字节的内容。

我在两个实体之间有一个 ManyToOne 关系：Usuario 和 Departamento，有些用户没有任何部门，我想让实体 Usuario 中的字段 departamento 可以为空，如何制作这个。我的代码如下所示：

<?php

namespace CECMED\TarifaBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * Usuario
 *
 * @ORM\Table()
 * @ORM\Entity(repositoryClass="CECMED\TarifaBundle\Entity\UsuarioRepository")
 * @UniqueEntity("email")
  */
class Usuario implements UserInterface{

    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     * @Assert\NotBlank(message="No debe dejar este campo vacío")
     * @ORM\Column(name="nombre", type="string",unique=true, length=255)
     */
    private $nombre;

    /**
     * @var string
     * @Assert\NotBlank(message="No debe dejar …

当我尝试使用错误的凭据登录时,它会显示"再次尝试,错误的凭据",但在输入正确的凭据后,它会显示错误找不到"GET /"的路由(来自" http:// localhost/bdayProj/web/app_dev. php/login ").以下是我的security.yml的配置

security:
encoders:
    FOS\UserBundle\Model\UserInterface: bcrypt

role_hierarchy:
    ROLE_ADMIN:       ROLE_USER
    ROLE_SUPER_ADMIN: ROLE_ADMIN

# http://symfony.com/doc/current/book/security.html#where-do-users-come-from-user-providers
providers:
    in_memory:
        memory: ~

    fos_userbundle:
        id: fos_user.user_provider.username

firewalls:
    # disables authentication for assets and the profiler, adapt it according to your needs
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false

    main:
        pattern: ^/
        form_login:
            provider: fos_userbundle
            csrf_token_generator: security.csrf.token_manager
        logout:    true
        anonymous: true
        # activate different ways to authenticate

access_control:
        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY } …

我想将所有返回“命令”文件保存在日志文件中

<?php

namespace LogicielBundle\Command\Cron;

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class MailRapportDometechCommand extends ContainerAwareCommand
{

    protected function configure()
    {
       $this
        ->setName('logiciel:mail_rapport_preparation_dometech')
    ;
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $output->writeln('. <bg=black;fg=white>Log color ...</>');

        $logFile = fopen('app/CommandLogs/MailRapportDometech/compteur.txt', 'w+');
        fputs($logFile, 'Test ... how to have $output data ?');
        fclose($logFile);

    }
}

如果可能的话，如果有错误，请给我发送电子邮件:) 谢谢:)
